Description

[Detailed explanation of the invention] This product can be attached to surfaces such as walls and floors, and can be easily peeled off when re-covering as needed, and can be applied to smooth surfaces without causing any damage to the surfaces of walls, floors, etc. The present invention relates to a decorative sheet that can be used as a decorative sheet.

Traditionally, decorative sheets have been used as a part of interior decoration on walls,
These decorative sheets are pasted on surfaces such as floors to create a sense of beauty, but these decorative sheets are later replaced with new decorative sheets according to preference or when the decorative sheets themselves become obsolete, but in this case, the old decorative sheet walls, When peeling from surfaces such as floors, peeling is done from the adhesive surface between the old decorative sheet and the surface of the wall, floor, etc., so it is easy to peel. Peeling force is required, and even if it is peeled off, the old decorative sheet is not peeled off uniformly, and fragments of the base material of the old decorative sheet stick to walls and other surfaces in various places, resulting in so-called uneven peeling, resulting in a smooth surface. That was extremely difficult.

Therefore, in order to apply a new decorative sheet smoothly and neatly, it is necessary to take the troublesome effort of wiping off the stuck base material fragments and adhesive on walls and other surfaces with a suitable solvent or using a spatula. The surface was cleaned and smoothed before pasting a new decorative sheet.

The present invention was developed in view of the above-mentioned problems, and embodiments thereof will be described below with reference to the accompanying drawings.

FIG. 1 is a sectional view showing a state in which the decorative sheet of the present invention pasted on a wall surface is peeled off.

In the figure, reference numeral 1 denotes a decorative sheet main body, which consists of a decorative base sheet 2 made of a flexible synthetic resin material such as polyvinyl chloride, and a separable backing material 3 with an adhesive 4 on the back side. It is attached.

This backing material 3 is a glass fiber non-woven fabric or a liner 5
, 5' are integrally bonded together via a polyolefin layer 6 such as polyethylene as an intermediate layer.

Reference numeral 7 denotes a surface such as a wall or floor, onto which the decorative sheet main body 1 is adhered via an adhesive 8.

In the above, the adhesive 4 used for adhering the decorative base sheet 2 such as polyvinyl chloride and the backing material 3 is, for example, P
VC latex, PVC paste, acrylic type, or vinyl acetate type may be appropriately selected and used.

The adhesive 8 used to bond the backing material 3 to the surface to which it is attached, such as a wall, is a vinyl acetate-based, nitrile-based, or rubber-based emulsion. Examples of applicable formulations include (vinyl acetate: 80%, solvent : 10%, epoxy system: 10
%).

The decorative sheet formed as described above is pasted onto a surface 7 such as a wall using an adhesive 8 which has a stronger adhesive force than the adhesive force between each layer of the decorative sheet. The most important thing is the adhesive strength between the glass fiber nonwoven fabric or liner of the polyolefin layer provided as an intermediate layer of the backing material in the interrelationship of the adhesive strength between each layer of the decorative sheet and between the decorative sheet and the surface to which it is attached. is to make it relatively inferior compared to others.

The effects of the present decorative sheet will be described below.

1 When pasted to a surface such as a wall, when peeled off after being pasted to the surface, the adhesive strength of the polyolefin, which is the intermediate layer of the backing material, which can be separated into layers as described above, is the adhesive force between each layer of the decorative sheet and the decorative sheet and the pasted surface. Since the adhesion is inferior to the adhesion to the surface, the separable backing material can be delaminated from the intervening polyolefin layer and peeled off very easily.

2. On the surfaces of walls, floors, etc., the separated backing material is glass fiber non-woven fabric, or the liner remains on the flat layer surface, so it is necessary to peel off the walls, floors, etc. when conventional decorative sheets are removed. There is no need for any post-treatment to clean and smooth the top surface, and the new decorative sheet can be applied directly to the flat and rough surface of the glass fiber non-woven fabric or liner left on the wall or other surface. Reupholstery work can also be done quickly and efficiently.

3. In this proposed decorative sheet, a laminate of glass fiber nonwoven fabric - polyolefin layer - glass fiber nonwoven fabric, or liner - polyolefin layer - liner is used as the layer-separable backing material. The polyolefin layer has the effect of blocking moisture from concrete surfaces, and this polyolefin layer also prevents the adhesive used when attaching this decorative sheet to surfaces such as walls and floors from penetrating deep into the decorative sheet. It also gives the sheet its own stiffness, making it easier to handle the decorative sheet during construction.

4. In the case of a decorative sheet using glass fiber nonwoven fabric - polyolefin layer - glass fiber nonwoven fabric as the backing material, it can be neatly attached to corners such as walls due to the dimensional stability and bendability of the glass fiber nonwoven fabric itself. I can do it.

On the other hand, in the case of a decorative sheet using a liner-polyolefin layer-liner as a backing material, the cushioning properties, heat retention properties, and toughness provided by the liner are preferably imparted to the decorative sheet itself.

Claims (1)

[Scope of utility model registration request] A backing material having a polyolefin layer as an intermediate layer is pasted on the back side of the decorative base sheet, and when the backing material is peeled off after being pasted onto a surface such as a wall or floor using an adhesive, the backing material is removed. The adhesive force of the polyolefin which is the intermediate layer of the backing material is compared with the adhesive force between each layer of the decorative sheet and the adhesive force between the decorative sheet and the surface to which it is attached, so that the material is separated at the polyolefin layer. A decorative sheet characterized by having a structure that is inferior to that of a decorative sheet.
